The present invention provides a bogie for a guide rail type vehicle that runs along a predetermined guideway. The bogie includes a turn frame connected to a vehicle body; an axle turnably mounted to the turn frame via bearings and; a guide frame mounted to the axle; a first pair of guide wheels rotatably provided at a vehicle body end side portion of the guide frame; a second pair of guide wheels rotatably provided at a vehicle body center side portion of the guide frame; a stopper provided so as to project from an upper surface on a vehicle body side of the axle toward the vehicle body; and a pair of stopper receivers arranged facing each other at intervals from the stopper in a vehicle lateral direction.

Bogie for guide rail type vehicle

A track-guided vehicle wheel truck prevents wear and deterioration of a guide wheel and a guide rail, and ensures running stability while simplifying the structure. In the track-guided vehicle wheel truck, a guide frameto which a guide wheelguided by a guide railis mounted, can turn relative to a steering axleof a running wheel. A support shaftis provided on an axle bracketprovided in the steering axleso as to be movable in the vehicle front and rear direction by straddling the steering axle. A link levercapable of interlocking the turning of the guide frameand the steering of the running wheelis provided along the vehicle front and rear direction. A vehicle end-side end part of the link leveris rotatably mounted to a connecting rodthat enables the steering of the running wheel. An intermediate part of the link leveris rotatably mounted to the guide frame. A long holeextending in the vehicle front and rear direction is provided in a center-side end part of the link lever. The long holeand the support shaftare rotatably engaged with each other at a given position.

Track-guided vehicle wheel truck

The present invention provides a bogie for a guide rail type vehicle running on a predetermined guideway. The bogie of the present invention includes an axle in which steerable running wheels are mounted, a guide frame arranged under the axle, a pair of first guide wheels provided rotatably in a vehicle body end-side part of the guide frame, a pair of second guide wheels provided rotatably in a vehicle body center-side part of the guide frame, a pair of tie rod arms that is attached to the axle and are formed so as to extend from the axle to the vehicle body center-side, and a pair of tie rods each connecting the guide frame to each of the pair of tie rod arms.

In a track-guided vehicle wheel truck, a guide frame can be turned relative to a steering axle of a running wheel. A support shaft is adjustably provided on the guide frame. A receiving member is provided projecting toward the vehicle end side. A link lever capable of interlocking the turning of the guide frame and the steering of the running wheel, is provided along the vehicle front and rear direction. A center-side end part of the link lever is rotatably mounted to the receiving member. A vehicle end-side end part of the link lever is rotatably mounted to a connecting rod that enables the steering of the running wheel. A long hole extending in the vehicle front and rear direction, is provided in an intermediate part of the link lever. The long hole and the support shaft are rotatably engaged with each other at a given position.
